# OpenTracing Apache HttpClient 

Apache HttpClient instrumentation.

## Configuration

```java

GlobalTracer.register(tracer);

HttpClient httpClient = new TracingHttpClientBuilder()

    .build();

//custom configuration

HttpClient httpClient = new TracingHttpClientBuilder(

        redirectStrategy, 

        redirectHandlingDisabled,

        GlobalTracer.get(),

        spanDecorators)

    .build();

```

## Linking to parent span

If parent span context is not passed created client spans will be in a new trace.

### SpanManager

```java

spanManager.activate(parentSpan); // called in the same thread as client.execute()

client.execute(new HttpGet("url"));

```

### Manually 

```java

BasicHttpContext basicHttpContext = new BasicHttpContext();

basicHttpContext.setAttribute(Constants.PARENT_CONTEXT, parentSpan.context());

client.execute(new HttpGet("url"), basicHttpContext);

```

## Development

```shell

./mvnw clean install

```
